alpha
The alpha factor.
sensitivity
An integer value that represents the mouse sensitivity, in percent. Possible values are 1 - 100. Default is 100. A value of 100 indicates that the amount of change in the action is equal to the amount of movement of the mouse. For example, if the mouse is moved 1 pixel, the action changes by 1 unit. A value of 50 indicates that the amount of change in the action is 50% of the amount of mouse movement. For example, if the mouse is moved 2 pixels, the action only changes by one unit.
circularMouseMove
true to make the mouse reset when it reaches the side of the container (when the mouse resets, if it is dragged to one side of the container, it will disappear from that side and reappear on the opposite side of the container); false otherwise.
cursor
Default cursor for the action.
Initializes a new instance of the MedicalViewerAlpha class. with a specified alpha factor, mouse sensitivity, mouse behavior and cursor.
